Magnets, Installation

A magnet is required for each
transducer. This must be ordered
separately. ➥ ➥ ➥ ➥ ➥ Fig. 3-4.
For mounting the magnet we rec-
ommend to use non-magnetizable
material. ➥ ➥ ➥ ➥ ➥ Fig. 3-2.

Cable axial and radial

Cable length max. 500 m;
Ø 6 to 8 mm. Longer lengths may
be used if construction, shielding
and routing are such that external
noise fields will have no effect on
signal integrity.

High noise immunity on the line
between the transducer and proc-
essor is provided by the differen-
tial line drivers used for the RS
485/422 interface. The differential
signal is carried to the processor,
which makes it available as analog
or digital information for further
processing.

4 Wiring (cont.)
Note the following when mak-
ing electrical connections:
System and control cabi-
net must be at the same
ground potential.
To ensure the electromagnetic
compatibility (EMC) which Balluff
warrants with the CE Mark, the
following instructions must be
strictly followed.
BTL transducer and the proces-
sor/control must be connected
using shielded cable.
Shielding: Copper filament
braided, 85 % coverage.
The cable shield must be grounded
on the control side, i.e., connected
to the protection ground.
Pin assignments can be found in
➥ ➥ ➥ ➥ ➥ Table 4-1. Connections on the
controller side may vary according
to the controller and configuration
used.
To avoid coupled noise, avoid
proximity to high-current lines
when routing cable between
transducer, controller and power
supply. Inductive coupled noise
from AC harmonics (e.g., from
phase controls) are especially
critical, against which the cable
shield offers very little protection.

they must never be connected to
the shield.
